[jira] [Created] (HIVE-23275) Represent UNBOUNDED in window functions in CBO correctly

Jesus Camacho Rodriguez created HIVE-23275:
----------------------------------------------

             Summary: Represent UNBOUNDED in window functions in CBO correctly
                 Key: HIVE-23275
                 URL: https://issues.apache.org/jira/browse/HIVE-23275
             Project: Hive
          Issue Type: Improvement
          Components: CBO
            Reporter: Jesus Camacho Rodriguez
            Assignee: Jesus Camacho Rodriguez


Currently we use a bounded representation with bound set to Integer.MAX_VALUE, which works correctly since that is the Hive implementation. However, Calcite has a specific boundary class {{RexWindowBoundUnbounded}} that we should be using instead.
